On today's A Healthy You & Carol Alt, Carol welcomed Dr. Nicholas Gonzalez, the author of "What Went Wrong: The Truth Behind the Clinical Trial and Enzyme Treatment of Cancer."

And as Alt revealed, she's also a personal patient of Gonzalez's, whose cancer therapy is based on the early 20th Century work of Dr. Beard.

"What we do has a hundred-year history," said Gonzalez, explaining that Dr. Beard wrote papers on the anti-cancerous effect of pancreatic enzymes. While working at Sloan-Kettering, Gonzalez had also met a man named Dr. Kelly, an orthodontist who used Beard's research to help with his own cancer diagnosis.

"He had been diagnosed with pancreatic cancer, and was told he had six weeks, eight weeks to live," Gonzalez recounted. Then, after Kelly began treating himself with pancreatic enzymes, Gonzalez said he eventually became well, and cancer patients soon started to seek his help.

Gonzalez also believes that these enzymes — which already exist in our own bodies, though maybe not in the right quantities — have the potential to kill cancer cells. Though research is still ongoing, he suspects that they attack the proteins on the malignant cells, which leads to the cells themselves dying. "They seem to kill them, digest them like a piece of meat," said Gonzalez.
